Some hydroxyquinoline carboxylic acids and their conjugate acids and bases were characterized by 13 C and 15 N NMR spectroscopy in solution and in the solid state. Differences in 13 C and, in particular, 15 N chemical shift patterns allow to distinguish between individual tautomers and confirm the p
